A 1031 exchange in Massachusetts lets you sell investment real estate and reinvest in like-kind property while deferring the tax on the gain. The federal rules apply the same way everywhere. Massachusetts has changed recently in ways that matter: a 4% surtax now lands on large gains, the state added a nonresident withholding step in late 2025, and Massachusetts is a clawback state. We act as your qualified intermediary, holding the proceeds and handling the documentation so the exchange holds from sale to closing.

How much is capital gains tax on real estate in Massachusetts?
Massachusetts taxes long-term capital gains at a flat 5%, but a 4% surtax, the so-called millionaire's tax, applies to taxable income above roughly $1 million (the threshold is indexed each year), so a large gain that pushes you over that line is effectively taxed at 9% on the excess. Short-term gains are taxed at a higher 8.5%. Those rates sit on top of the federal tax an exchange also defers:
- Long-term capital gains at 0%, 15%, or 20%, with the 20% rate applying above $545,500 of taxable income for single filers and $613,700 for married couples filing jointly in 2026.
- The 3.8% Net Investment Income Tax above $200,000 of modified adjusted gross income for single filers, $250,000 for married couples.
- Depreciation recapture, taxed as unrecaptured Section 1250 gain at up to 25%.
Because a sizable property gain can easily clear $1 million, the surtax is a real factor here, and it is exactly the kind of liability a 1031 defers. Massachusetts conforms to Section 1031, so a properly structured exchange defers the federal and the Massachusetts tax. The full federal framework is in our main 1031 exchange guide.
Massachusetts added nonresident withholding in late 2025
Effective November 1, 2025, Massachusetts requires withholding when a nonresident sells real estate with a gross sales price of $1 million or more. The closing agent files Form NRW and withholds either 4% of the gross sales price by default, or, if the seller documents the actual gain, an alternative of 5% for individuals or 8% for corporations on the net gain. Every seller of a property at or above $1 million must provide a Transferor's Certification at closing, even when no withholding is due.
In a 1031 exchange you use that certification to establish that the gain is not recognized, supported by your intermediary's documentation, so the withholding is not collected. Because this requirement is new, many sellers and even some closing agents are still adjusting to it, so getting the certification right ahead of closing is the way to keep your cash from being held back. Note the two separate $1 million lines that can both apply to a large deal: the surtax attaches to income over about $1 million, and the withholding attaches to a sales price of $1 million or more.
Massachusetts 1031 exchange rules and timeline
The federal deadlines govern, and they are strict:
- 45-day identification. Identify replacement property in writing within 45 days of the sale.
- 180-day closing. Close within 180 days of the sale, or by your return due date including extensions, whichever is earlier.
- No constructive receipt. Proceeds go to your qualified intermediary, never to you.
- Equal or greater value and debt. Reinvest all net proceeds and match or exceed the relinquished value and debt, or the shortfall is taxable boot.
- Same taxpayer. The entity that sold must be the entity that buys.
The Massachusetts clawback
Massachusetts is one of four clawback states, with California, Oregon, and Montana. When you sell Massachusetts property, exchange into replacement property elsewhere, and later sell that replacement in a taxable transaction, Massachusetts expects to tax the gain that accrued while the property was in the state. The exchange defers the tax, but Massachusetts retains its claim on the Massachusetts-source gain, so plan for it if you reinvest out of state.
1031 exchanges across Massachusetts markets
Greater Boston anchors the state's exchange volume, and its defining feature is life-sciences and laboratory real estate across Cambridge, Boston, and the surrounding suburbs, one of the strongest commercial niches in the country, alongside multifamily and office. Worcester and Springfield offer multifamily and commercial property at lower entry prices, and Cape Cod carries second-home and investment demand. Massachusetts property tax is governed by Proposition 2½, which limits how fast a municipality's total levy can grow, though effective rates still vary by city and town and belong in your replacement-property math.
Common Massachusetts 1031 exchange mistakes
- Not providing the Transferor's Certification on a $1 million-plus sale, so the new nonresident withholding is collected and tied up.
- Overlooking the 4% surtax on gains above roughly $1 million, which a 1031 can defer.
- Forgetting the Massachusetts clawback when reinvesting out of state.
- Taking receipt of the proceeds, or missing the 45-day identification window.
Start your Massachusetts 1031 exchange
Set up your exchange before your relinquished property closes, so the Transferor's Certification is in place at the table and the proceeds never reach your hands. Contact our team to begin, or to talk through a specific deal.
Frequently asked questions
How much is capital gains tax on real estate in Massachusetts?
Long-term gains are taxed at a flat 5%, plus a 4% surtax on taxable income above roughly $1 million, for an effective 9% on the excess. Short-term gains are taxed at 8.5%. Federal capital gains tax applies on top.
Does Massachusetts have nonresident withholding on a property sale?
Yes, as of November 1, 2025, for sales with a gross price of $1 million or more. The default is 4% of the price on Form NRW, with an alternative on net gain. In a 1031 you certify no recognized gain to avoid it.
Does Massachusetts have a 1031 clawback?
Yes. It is one of four clawback states. If you exchange Massachusetts property into another state and later sell the replacement in a taxable transaction, Massachusetts taxes the gain that accrued in the state.
Do I need a qualified intermediary for a Massachusetts 1031 exchange?
Yes. The intermediary must hold the proceeds and facilitate the exchange, and supports the certification at closing. Engage one before the relinquished property closes.
